A teacher is speaking in a classroom, but loud noise from outside makes it difficult for students to hear the message. What type of communication barrier is this?

Answer and explanation

Correct answer: Physical barrier

External noise is an environmental obstruction that physically interferes with the sound reaching the learners. It is therefore a physical barrier. A language barrier involves different languages or vocabulary, an emotional barrier involves feelings such as fear or anger, and a cultural barrier involves differences in norms or meanings. None of those is the direct cause here.
